Re: Invisible colons in Emacs Info.

[Karl Berry]

    still recognize some of those old entries (as long as such tweaking does
    not impact valid cases).

Of course that's fine and desirable.

I guess that if there are no other colons or periods in the menu entry
after the first :, it can be unambiguously parsed. (Not counting the ::
form, of course.)  But if there are following colons or periods, then it
seems the space is needed.
